ChiaoGoo Knit RED™ surgical stainless steel circulars have a smooth, satin sheen finish. They feature memory-free, multi-strand, steel cable coated with red nylon so your yarn will slide right over them. An ergonomically designed bend in the longer needle tips eases hand fatigue. No guessing about the needle size; it’s laser-imprinted on each needle. Reports rave about the smooth joins! We’re testing these needles out, so please let us know how you like them!
